Alstroemeria plant named ‘Zalsaris’

ABSTRACT

A new and distinct cultivar of  Alstroemeria  plant named ‘Zalsaris’, characterized by its erect and strong flowering stems; vigorous growth habit; purple and white-colored flowers; and excellent postproduction longevity.

Botanical designation: Alstroemeria hybrida.

Cultivar denomination: ‘Zalsaris’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofAlstroemeria plant, botanically known as Alstroemeria hybrida,commercially used as a cut flower Alstroemeria, and hereinafter referredto by the name ‘Zalsaris’.

The new Alstroemeria plant is a product of a planned breeding programconducted by the Inventor in Rijsenhout, The Netherlands. The objectiveof the breeding program is to create new cut flower Alstroemeriacultivars with desirable flower and plant qualities, attractive foliageand flower coloration and excellent postproduction longevity.

The new Alstroemeria plant originated from a cross-pollination made bythe Inventor in Rijsenhout, The Netherlands in May, 2002, of aproprietary Alstroemeria hybrida selection identified as code number00141-005, not patented, as the female, or seed, parent with aproprietary Alstroemeria hybrida selection identified as code number97246-003, not patented, as the male, or pollen, parent. The newAlstroemeria was discovered and selected by the Inventor as a floweringplant from within the progeny of the stated cross-pollination in acontrolled greenhouse environment in Rijsenhout, The Netherlands inJune, 2003.

Asexual reproduction of the new Alstroemeria plant by rhizome divisionsin a controlled greenhouse environment in Rijsenhout, The Netherlandssince September, 2003, has shown that the unique features of this newAlstroemeria plant are stable and reproduced true to type in successivegenerations.

SUMMARY OF THE INVENTION

Plants of the new Alstroemeria have not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment and cultural practices such as temperature andlight intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Zalsaris’. These characteristics incombination distinguish ‘Zalsaris’ as a new and distinct cultivar ofAlstroemeria plant:

-   -   1. Erect and strong flowering stems.    -   2. Vigorous growth habit.    -   3. Purple and white-colored flowers.    -   4. Excellent postproduction longevity.

Plants of the new Alstroemeria can be compared to plants of the femaleparent selection. Plants of the new Alstroemeria differ from plants ofthe female parent selection primarily in stem length as plants of thenew Alstroemeria have shorter stems than plants of the female parentselection.

Plants of the new Alstroemeria can be compared to plants of the maleparent selection. Plants of the new Alstroemeria differ from plants ofthe male parent selection primarily in flower color as plants of themale parent selection have purple and yellow-colored flowers.

Plants of the new Alstroemeria can be compared to plants of Alstroemeriahybrida ‘Zalsanyx’, disclosed in U.S. Plant Pat. No. 18,962. Inside-by-side comparisons conducted in Rijsenhout, The Netherlands,plants of the new Alstroemeria differed primarily from plants of‘Zalsanyx’ in stem length as plants of the new Alstroemeria had shorterflowering stems than plants of ‘Zalsanyx’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearanceof the new Alstroemeria, showing the colors as true as it is reasonablypossible to obtain in colored reproductions of this type. Colors in thephotograph may differ slightly from the color values cited in thedetailed botanical description which accurately describe the colors ofthe new Alstroemeria. The photograph comprises a side perspective viewof a typical flowering stem of ‘Zalsaris’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations andmeasurements describe plants of the new Alstroemeria grown inRijsenhout, The Netherlands in a glass-covered greenhouse in groundbeds. During the production of the plants, day temperatures ranged from15° C. to 20° C., night temperatures ranged from 10° C. to 15° C. andlight levels averaged 5,000 lux. Plants used for the photograph anddescription had been growing for one year. The photograph and thedescription were taken in the late summer. Color references are made toThe Royal Horticultural Society Colour Chart, 1995 Edition, except wheregeneral terms of ordinary dictionary significance are used.
